Description

Technical Field

[0001] This utility model relates to the field of angle detection technology, and in particular to a seat angle detection system. Background Technology

[0002] With the diversification of car models and the increase in demand for car interiors, car seats also come in various types. When a vehicle leaves the factory, the angle of the seat back is often tested. If the angle of the seat back is not within the preset angle range, it needs to be adjusted so that the angle of the seat back conforms to the preset angle. This ensures that the seat can be fixed within a comfortable angle range so that passengers can sit comfortably.

[0003] Currently, seat angle adjustment is performed directly on the conveyor line. When the seats are being transported on the conveyor line, operators manually check the seat back angle using a detection device. If the seat back angle is not within the preset angle range, the operators will stop the entire conveyor line and then adjust the seat back angle to meet the preset angle range. However, this detection method results in excessive labor intensity for the operators and low detection efficiency.

[0004] Therefore, it is necessary to provide a new seat angle detection system to solve the above-mentioned technical problems. Utility Model Content

[0016] In one embodiment, the second angle detection component includes a second angle detector, a third compression spring, a fourth compression spring, a horizontal fixing plate, a first fixing plate, a second fixing plate, and a third fixing plate. The first fixing plate, the second fixing plate, and the third fixing plate are spaced apart in the horizontal direction.

The second angle detector is mounted on the side of the third fixing plate opposite to the second fixing plate and is used to abut against the backrest of the seat.

[0017] In one embodiment, the second base plate is provided with two linear bearing slide rails, which are respectively disposed on both sides of the rodless cylinder. The bottom of the second angle detection component is provided with two second sliders, which are slidably mounted on the two linear bearing slide rails.

[0020] In the above scheme, the seat angle detection system includes a seat conveyor line, a first angle detection device, a second angle detection device, and a controller. The seat conveyor line includes a first-layer conveyor line and a second-layer conveyor line. The seat conveyor line is used to transport seats from the second-layer conveyor line to the first-layer conveyor line. A first blocker is provided at the inlet of the first-layer conveyor line, and a first stop switch is provided on the first-layer conveyor line.

The controller is signal-connected to the first angle detection device, the second angle detection device, the first blocker, and the second blocker.Specifically, the seats are placed into the second-level conveyor line through its inlet. The second-level conveyor line then transports the seats to the second positioning switch. The second positioning switch transmits a signal to the controller, which activates the second stopper. The second stopper prevents subsequent seats from entering the second conveyor line. Simultaneously, a second angle detection device detects the seat backrest angle. When the seat backrest angle meets a preset range, the controller stops the second stopper, allowing subsequent seats to enter the second-level conveyor line. The second-level conveyor line then transports the detected seats to the first-level conveyor line, which can be achieved using a gripper. The seats are either moved to the first conveyor line or lowered to the first conveyor line using a lifting device; these are conventional techniques in existing technology. The first conveyor line then transports the seats to its edge for mounting. When the seat back angle does not meet the preset range, the controller activates the second stopper to prevent subsequent seats from entering the second conveyor line. The second conveyor line continues to transport the seats to the first conveyor line. When the seat reaches the first positioning switch, the first positioning switch sends a signal to the first stopper, preventing the seat from moving out of the first conveyor line. The first angle detection device measures the backrest angle of the seat. If the current backrest angle is within the preset range, the first angle detection device drives the first stop to stop, allowing the seat to be moved out of the first layer of the conveyor line to the side after detection, and then mounted. If the current backrest angle is not within the preset range, the operator adjusts the backrest angle. There are two adjustment methods: the first is to insert a terminal and adjust the backrest angle using a handle; the second is to adjust the backrest angle using the seat's knob. After adjustment, if the first angle detection device detects that the backrest angle is within the preset range, the first angle detection device drives... The first stopper stops operating, allowing the seat that has completed the inspection to be moved out of the first conveyor line to the side of the line. The seat is then mounted, thus completing the adjustment of the abnormal seat. The operator then presses the operation completion button to reset the second stopper, allowing the seat to continue entering the second conveyor line, and repeats the above steps. This utility model achieves automatic detection of the seat back angle through the first and second stop switches, and prevents the seat from entering the second conveyor line and from moving out of the first conveyor line through the first and second stoppers. This eliminates the need to stop the entire seat conveyor line, greatly improving the inspection efficiency. Attached Figure Description

[0035] To achieve the above objectives, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5This utility model proposes a seat angle detection system, including a seat conveyor line, a first angle detection device 2, a second angle detection device 3, and a controller 4. The seat conveyor line includes a first-layer conveyor line 11 and a second-layer conveyor line 12. The seat conveyor line is used to transport seats from the second-layer conveyor line 12 to the first-layer conveyor line 11. A first blocker is provided at the inlet of the first-layer conveyor line 11, and a first position switch 111 is provided on the first-layer conveyor line 11. A second blocker is provided at the inlet of the second-layer conveyor line 12, and a second position switch 121 is provided on the second-layer conveyor line 12. The first blocker is used to prevent or allow the seat to move out of the first-layer conveyor line 11, and the second blocker is used to prevent or allow the seat to enter the second-layer conveyor line 12. The first angle detection device 2 is located on the first-layer conveyor line 11, and the first blocker is signal-connected to the first position switch 111. The second angle detection device 3 is located on the second-layer conveyor line 12. The controller 4 is signal-connected to the first angle detection device 2, the second angle detection device 3, the first blocker, and the second blocker.Specifically, the seats are placed into the inlet of the second-level conveyor line 12. The second-level conveyor line 12 then transports the seats to the second positioning switch 121. The second positioning switch 121 transmits a signal to the controller 4, which controls the second stopper to operate. The second stopper prevents subsequent seats from entering the second conveyor line. At the same time, the second angle detection device 3 detects the backrest angle of the seats. When the backrest angle of the seats meets the preset range, the controller 4 controls the second stopper to stop operating, allowing subsequent seats to enter the second-level conveyor line 12. Simultaneously, the second-level conveyor line 12 transports the detected seats to the first-level conveyor line 11, which can be achieved by using a gripper to move the seats to the first-level conveyor line 11. The first conveyor line 11 can also be used to lower the seats to the first conveyor line 11 via a lifting device; these are conventional techniques in the prior art. The first conveyor line 11 then transports the seats to its side for mounting. In fact, transporting seats from the second layer to the first layer is a common feature in existing technology. When the seat back angle does not meet the preset range, the controller 4 controls the second blocker to continue operating, preventing subsequent seats from entering the second conveyor line 12. The second conveyor line 12 continues to transport the seats to the first conveyor line 11. When the seat reaches the first positioning switch 111, the first positioning switch 111... The signal is transmitted to the first stopper, which prevents the seat from moving out of the first layer of the conveyor line. The first angle detection device 2 measures the backrest angle of the seat. If the current backrest angle is within the preset range, the first angle detection device 2 drives the first stopper to stop, allowing the seat to move out of the first layer of the conveyor line 11 and onto the line. If the current backrest angle is not within the preset range, the operator adjusts the backrest angle. There are two methods for adjustment: the first is to insert a terminal and adjust the backrest angle using a handle; the second is to adjust the backrest angle using the seat's knob. After adjustment, the first angle detection device 2 detects that the seat backrest angle is within the preset range. The first angle detection device 2 drives the first stopper to stop operating, allowing the seat that has completed the detection to move out of the first layer conveyor line 11 to the side of the line, and then mount the seat. This completes the adjustment of the abnormal seat. The operator then presses the operation completion button to reset the second stopper and allows the seat to continue entering the second layer conveyor line 12, and then repeats the above steps. In this embodiment, the automatic detection of the seat back angle is realized by the first stop switch 111 and the second stop switch 121. The first stopper and the second stopper prevent the seat from entering the second layer conveyor line 12 and prevent the seat from moving out of the first layer conveyor line 11. This eliminates the need to stop the entire seat conveyor line, greatly improving the detection efficiency.

[0036] Please see Figure 1 and Figure 3In one embodiment, the first angle detection device 2 includes a first bracket 21, a first angle detection component 22, a first telescopic cylinder 23, and a first mounting rod 24. The first bracket 21 is mounted on the first layer conveyor line 11. A first slider 241 is provided on the first mounting rod 24. A slide rail 211 is provided on the first bracket 21 along the vertical direction. The first slider 241 is slidably mounted on the slide rail 211. The first angle detection component 22 is mounted on the first mounting rod 24. The cylinder body of the first telescopic cylinder 23 is mounted on the first bracket 21. The extension rod of the first telescopic cylinder 23 is connected to the first mounting rod 24. Specifically, to avoid interference between the first angle detection device 2 and the clamp at the third-row seat pick-up port, a first telescopic cylinder 23 is provided. Under normal conditions, the first telescopic cylinder 23 is in the extended state, which raises the first angle detection component 22 upwards, thus preventing interference. When the seat reaches the detection position, it is conveyed to the first positioning switch 111. The first positioning switch 111 transmits a signal to the first angle detection component 22 and the first stopper. The first stopper prevents the seat from moving out of the first conveyor line 11. At this point, the first telescopic cylinder 23 needs to be activated, causing its extension rod to retract and lower the first angle detection component 22 to the seat position for angle detection. The activation of the first telescopic cylinder 23 can be done manually or by... The telescopic cylinder 23 is connected to the first position switch 111 to enable the automatic operation of the first telescopic cylinder 23. If the measured angle meets the preset range, the controller 4 controls the first stopper to release the seat. If the angle does not meet the preset range, the first stopper remains in the blocking state, and the system prompts for manual intervention. The operator makes adjustments, and after the adjustments are completed, the system is tested again until it meets the requirements. Then, the operation completion button is pressed, the entire system is reset, and the seat continues to be released into the second layer conveyor line 12. The first telescopic cylinder 23 retracts, and the first mounting rod 24 rises and resets. Similarly, the first telescopic cylinder 23 can be operated manually or automatically. The guiding design of the first slider 241 and the slide rail 211 ensures that the vertical movement of the first angle detection component 22 is stable, avoiding deviation or shaking and improving the detection accuracy.

[0037] Please see Figure 4In one embodiment, the first angle detection component 22 includes a first base plate 221, a second telescopic cylinder 222, a first support plate 223, a second support plate 224, and a first angle detection component 225. The first support plate 223 and the second support plate 224 are spaced apart. The first support plate 223 is mounted on the top surface of the first base plate 221, and the first base plate 221 is mounted on the first bracket 21. The cylinder body of the second telescopic cylinder 222 is mounted on the first support plate 223, and the extension shaft of the second telescopic cylinder 222 passes through the first support plate 223 and is connected to the second support plate 224. The first angle detection component 225 is connected to the second support plate 224 and is used to abut against the back of the seat. When the seat moves to the first position switch 111, the second telescopic cylinder 222 is activated. The extension shaft of the second telescopic cylinder 222 extends, pushing the second support plate 224 toward the seat. At the same time, it pushes the first angle detection component 225 toward the seat until the first angle detection component 225 comes into contact with the seat back. The contact detection improves the accuracy of the detection. At the same time, the second telescopic cylinder 222 adjusts the contact force between the first angle detection component 225 and the seat back to prevent damage to the first angle detection component 225.

[0038] Furthermore, the second telescopic cylinder 222 can also be connected to the controller 4 via a signal. When the seat moves to the first position switch 111, the controller 4 will control the second telescopic cylinder 222 to extend, thereby enabling automated detection and further reducing the labor intensity of the operators.

[0039] Please see Figure 4 In one embodiment, the first angle detection component 22 further includes a guide rod 226. One end of the guide rod 226 is connected to the second support plate 224. A through hole is formed on the first support plate 223, and a sleeve 223a coaxially arranged with the through hole is provided on the first support plate 223. The other end of the guide rod 226 passes through the through hole and is slidably installed in the sleeve 223a. By providing the guide rod 226, when the second telescopic cylinder 222 drives the first angle detection component 225 to extend or retract, the guide rod 226 can follow and extend or retract in the sleeve 223a, thus playing a guiding role and preventing the second support plate 224 from deflecting or shaking during movement, thereby improving detection accuracy.

[0040] Please see Figure 4 Furthermore, the number of guide rods 226 is at least two, and the number of sleeves 223a is at least two. The two sleeves 223a are respectively set on both sides of the cylinder body of the second telescopic cylinder 222. The two guide rods 226 and the two sleeves 223a are set one-to-one. By setting such a structure, the second support plate 224 can be further prevented from deflecting or shaking during the movement.

[0041] Please see Figure 4 In one embodiment, the first angle detection component 225 includes a first angle detector 225a, a first compression spring 225b, a second compression spring 225c, a third support plate 225d, and a fourth support plate 225e. The first support plate 223, the second support plate 224, the third support plate 225d, and the fourth support plate 225e are spaced apart in the horizontal direction. The two ends of the first compression spring 225b are respectively connected to the second support plate 224 and the third support plate 225d. A first universal hinge seat 225f is provided on the side of the third support plate 225d away from the second support plate 224. The rotating end of the first universal hinge seat 225f is connected to the fourth support plate 225e. The two ends of the second compression spring 225c are respectively connected to the third support plate 225d and the fourth support plate 225e. The first angle detector 225a is installed on the side of the fourth support plate 225e away from the third support plate 225d and is used to abut against the back of the seat. During testing, the second telescopic cylinder 222 drives the first angle detector 225a to abut against the back of the seat. This causes the first angle detector 225a to fit against the backrest. The fourth support plate 225e, connected to the first angle detector 225a, rotates relative to the third support plate 225d via the rotating end of the first universal hinge 225f. This compresses the first compression spring 225b, while the second compression spring 225c is not only compressed but also bent. The second compression spring 225c, in conjunction with the backrest, presses the first angle detector 225a tightly. Simultaneously, the bending of the second compression spring 225c balances the weight of the first angle detector 225a and the reaction force of the backrest. The compression of the first compression spring 225b absorbs the excess stroke of the second telescopic cylinder 222 and acts as a buffer, preventing the backrest from impacting the first angle detector 225 and causing damage to it.

[0042] Please see Figures 5 to 7In one embodiment, the second angle detection device 3 includes a second bracket 31, a second base plate 32, a rodless cylinder 33, and a second angle detection component 34. The second bracket 31 is installed on the second layer conveyor line 12, the second base plate 32 is installed on the second bracket 31, the cylinder body of the rodless cylinder 33 is installed on the side of the second base plate 32 away from the second bracket 31, and the second angle detection component 34 is installed on the slider of the rodless cylinder 33. The second angle detection component 34 is used to abut against the back of the seat. When the seat moves to the second position switch 121, the rodless cylinder 33 is activated. The slider of the rodless cylinder 33 slides towards the seat, which pushes the second angle detection component 34 towards the seat until the second angle detection component 34 comes into contact with the seat back. The contact detection improves the accuracy of the detection. At the same time, the rodless cylinder 33 adjusts the contact force between the second angle detection component 34 and the seat back to prevent damage to the second angle detection component 34. Moreover, the rodless cylinder 33 has a long stroke and high operating accuracy. Compared with ordinary cylinders, the rodless cylinder 33 can maintain high positioning accuracy over a longer stroke range. The slider of the rodless cylinder 33 moves along the guide rail, which can avoid deviation or vibration and ensure that the detection component is in stable contact with the seat back.

[0043] Furthermore, the rodless cylinder 33 can also be connected to the controller 4 via a signal. When the seat moves to the second position switch 121, the controller 4 will control the slider of the rodless cylinder 33 to slide towards the seat, thus enabling automated detection and further reducing the labor intensity of the operators.

[0044] Please see Figure 7In one embodiment, the second angle detection component 34 includes a second angle detector 341, a third compression spring 342, a fourth compression spring 343, a horizontal fixing plate 344, a first fixing plate 345, a second fixing plate 346, and a third fixing plate 347. The first fixing plate 345, the second fixing plate 346, and the third fixing plate 347 are spaced apart horizontally. The first fixing plate 345 is mounted on the horizontal fixing plate 344, and the horizontal fixing plate 344 is mounted on the slider of the rodless cylinder 33. The third compression spring 342... Both ends are connected to the first fixing plate 345 and the second fixing plate 346 respectively. The second fixing plate 346 is provided with a second universal hinge seat 348 on the side away from the first fixing plate 345. The rotating end of the second universal hinge seat 348 is connected to the third fixing plate 347. Both ends of the fourth compression spring 343 are connected to the second fixing plate 346 and the third fixing plate 347 respectively. The second angle detector 341 is installed on the side of the third fixing plate 347 away from the second fixing plate 346. The second angle detector 341 is used to abut against the back of the seat. During testing, the slider of the rodless cylinder 33 moves towards the seat, which drives the second angle detector 341 to move towards the seat until it comes into contact with the seat back. The second angle detector 341 then fits against the backrest. The third fixing plate 347, connected to the second angle detector 341, rotates relative to the second fixing plate 346 via the rotating end of the second universal hinge 348. This compresses both the third compression spring 342 and the fourth compression spring 343, while the fourth compression spring 343 also bends. This allows the third compression spring 342 to work with the seat backrest to press the second angle detector 341 firmly. Simultaneously, the bending of the fourth compression spring 343 balances the weight of the second angle detector 341 and the reaction force of the seat backrest. The compression of the third compression spring 342 absorbs the excess stroke of the second telescopic cylinder 222 and acts as a buffer, preventing the seat backrest from impacting the second angle detection component 34 and causing damage to it.

[0045] Please see Figure 7In one embodiment, two linear bearing slide rails 321 are provided on the second base plate 32, and the two linear bearing slide rails 321 are respectively provided on both sides of the rodless cylinder 33. Two second sliders 349 are provided at the bottom of the second angle detection component 34, and the two second sliders 349 are slidably mounted on the two linear bearing slide rails 321. Limiting plates 321a are provided at both ends of the linear bearing slide rails 321, and the limiting plates 321a can abut against the second sliders 349. The second angle detection component 34 also includes a proximity switch 350, which is provided on the linear bearing slide rails 321. The proximity switch 350 is used to detect the distance between itself and the second sliders 349, and the proximity switch 350 is signal connected to the rodless cylinder 33. During the movement of the slider of the rodless cylinder 33, the second angle detection component 34 also moves accordingly. To prevent the second angle detection component 34 from shifting or wobbling during movement, two second sliders 349 are provided at the bottom of the second angle detection component 34. Linear bearing slide rails 321 are provided on both sides of the rodless cylinder 33, and the two second sliders 349 are slidably connected to the two linear bearing slide rails 321 respectively, thus playing a guiding role. Limiting plates 321a are provided at both ends of the linear bearing slide rails 321 to prevent the second sliders 349 from detaching from the linear bearing slide rails 321. At the same time, a proximity switch 350 is provided on the linear bearing slide rails 321, so that the extension distance of the second angle detection component 34 can be measured. The proximity switch 350 is connected to the rodless cylinder 33, and the extension distance of the second angle detection component 34 can be adjusted by setting the position of the proximity switch 350.

[0046] Please see Figures 5 to 7 In one embodiment, a screw 322 is provided at the bottom of the second base plate 32, and an elongated hole 311 is provided on the second bracket 31. The screw 322 is slidably mounted in the elongated hole 311, and the extending direction of the elongated hole 311 is the same as the sliding direction of the rodless cylinder 33. Due to the design of the screw 322 and the elongated hole 311, the second base plate 32 and all components mounted on it, such as the rodless cylinder 33 and the angle detection component, can be finely adjusted along the direction of the elongated hole 311 and in the height direction. This allows the system to adjust its height position according to different models or sizes of seats, thereby ensuring the accuracy and applicability of the detection.

[0047] Please see Figure 5 and Figure 6In one embodiment, the second angle detection component 34 further includes a transparent cover 351, which is mounted on the second base plate 32 to cover the second angle detection component 34. The transparent cover 351 has an opening 351a through which the second angle detection component 34 can extend. The transparent cover 351 can effectively prevent dust, oil, metal shavings, and other impurities from entering the detection component, avoiding sensor misjudgment or mechanical jamming caused by contamination. On automated production lines, there may be clamps, conveyor belts, or other moving parts around the equipment. The transparent cover 351 can act as a buffer and isolation to prevent the second angle detection component 34 from being damaged by external impacts. Using transparent materials such as acrylic or PC board to make the cover allows direct observation of the working status of the detection component without removing the cover, facilitating daily inspections and troubleshooting. When the system malfunctions, technicians can quickly determine whether the problem is mechanical or a signal feedback issue through the transparent cover 351, saving diagnostic time.

[0048] Please see Figure 3 Furthermore, a transparent cover 351 can be placed on the first base plate 221 to cover the first angle detection component 225. The structure is the same as the transparent cover 351 on the second base plate 32, which can also protect the first angle detection component 225.

[0049] The above are merely exemplary embodiments of this utility model and do not limit the scope of protection of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
